Contour cutting correx by hand…
It’s starting and we have a few orders now being placed for delivery as soon as we’re back in Jan.
One of which is 7 board printing and contour cut to shape (nothing too complex) and the customer is now away until Friday, which is cutting it fine to get the printed, cut 7 delivered by a trade printer for the end of next week.
Is it possible to cut correx with a jigsaw? Or any other handheld tool?

Depends on thickness but maybe a decent big pair of scissors would do it?

If it’s just going to be a pain doing it 7 times – and you think it might be faster to create one master template in 5mm PVC foamex (scalpel / stanley) and then d/s tape it to the correx and route round them (router table & follower bit)…always an option. (Rough hack it to size first).
Done lots of stuff this way.

Yes they’re no all identical that’s the thing, didn’t think of using a router to cut it though :thumbsup:
Customer has just said their deadline’s not fixed as they can’t get the artwork supplied, so no as urgent as they first made out!

A jigsaw makes a mess of the edges, as does a router.
A Stanley knife is your best bet if you are cutting it by hand. 3mm is quite easy to cut, 5mm is hard work, the 8mm is impossible.
I have a dragknife for my CNC that is basically a stanley blade on a bearing, which cuts it beautifully. -
Needs to be on a 6mm, customer’s moved the deadline so it should be able to off to a trade printer to sort out for us.

Cutting them with a dragging blade might not deliver good results, it depends how complex the shapes are. The reason is the partition between the grooves that sometimes might force your blade to a different direction than the one you want to cut.
The best results will be routing them. I can’t give you precise info here because we have a CNC with its own bits.
But there are 2 factors that matter: the bit and the speed.You need a bit designed to cut foamex/plastics.
The speed is essential. A low speed will leave rough edges. A high speed will make the bit going hot, the correx will tend to melt a little bit on the edges and you will end up with some sort of smooth "hair" on edges.The optimal speed will produce a clean cut on correx or foamex.
